I've been using astronomy gear for a while now, and for ages I've been annoyed by my astro cam glitching out and needing a reboot as it would refuse to take pictures randomly. And last night it refused to take any images... Until I unplugged it from the USB hub and plugged it into my laptop directly. Then it worked perfectly with no complaints. But the mini camera for guiding has no issues being plugged in via the hub, nor does the filter wheel, or focuser. This isn't some cheapo USB hub either. It's a £250 Pegasus power box advance V2 designed for astro kit. I could understand if cheapo hubs had issues (I have used off the shelf normal hubs which handled matters much worse than the Pegasus to be fair), but this is intended for use with astro equipment and I was very happy being able to get my laptop to scope cabling done through only two cables (one to USB hub and one to mount, since the hub and mount both want to be treated as rs232 devices or something weird like that so they didn't work daisy chained) That Pegasus box though takes 12v power, distributes it via 4 live ports and 2 PWM dew heater ports, and also acts as a USB3 hub and given the price shouldn't it be able to direct USB data properly like the USB controller in the laptop manages multiple ports? What am I missing here?

In the end I bit the bullet. Seems great so far as even in games where my performance hasn't quite tripled, everything is a lot smoother so I think it's been worth it. Thanks guys

With the exception of price this is roughly how I feel. In the UK I can buy a 4070 for similar prices to a 6800xt, with the 6800xt having the cheapest SKUs Not sure how low down the list I could/should go. In theory they should all conform to some minimum spec, and I don't intend to do any manual overclocking for sure. I do get a good feeling from the powercolour red dragon one however, and in the past I have read that PC have been a bit poor in the past but shown improvement during the RDNA lines? Thanks for your input btw!

I have a 1070 at the moment, 7 years strong. But I felt like an upgrade back when the 6000 and 30 series came out, and only held back because of the limited VRAM in the 30 series and pricing/availability. 2 years on, with 7000 and 40 series coming out, I was planning on waiting for a 7800xt of some sort to appear. But when Linus' review of the 4070 came out, I noticed that the 6800xt and the 7900xt were worryingly close in performance. So much so that I have a hard time believing the 7800xt will be appreciably faster than a 6800xt, meaning it will most likely be a gain in terms of power draw(?) If i take a 6800xt to be sort of "nvidia XX80 tier" in the lineup (6900xt and 6950 seem to have small difference in perf for big increase in cost), then the £560 I could pick one up for seems not too disproportionate to the £415 I paid for my 1070. So with that in mind: Based on the trends we're seeing with the GPU lineups now, would it even be worth waiting for a 7800xt to give me 5% more performance and a certain amount less power draw, or should I just buy a 6800xt now and enjoy it for the next 4-6ish years? Because at the moment the waters have calmed and plateaued in terms of pricing and cards (ha) have basically been put on the table, and as much as I don't like the idea, a 2 year old card still seems like a good option? I'm not fussed about raytracing (seemingly getting food framerates in RT games at 1440p up is still the realm of £900+ nvidia cards) or AI upscaling so an AMD card might be a good match for me anyhow? Only slight detraction from this is my 650w PSU (EVGA supernova G2), and if a 6800xt + R7 5800x would be overstressing it a bit. What are your thoughts about this upgrade?

I'm in a similar boat. 6800/xt seems a bit old now (2 year old cards) while also still being very expensive. 7800xt yet to even materialise in many rumours despite being 2 months on from the 7900 lineup launch. And when it does, it could present such a poor value/performance that I may as well have bought a 6800 card anyway... On another forum I have seen people saying AMD might not even release the 7800 lineup until 6800xt stock is fully wound down, in order to keep prices high. I don't know if that's realistic but it would be very bad for us if it is true.

The term "earrape" has been a thing on youtube memes since basically the platform's conception. There will be 30 year olds or older who had or have that term in their vocab, not just "youths"

A few weeks ago I noticed that the normally blue activity lights under the two drives in my WD 2-bay NAS had gone red. Files still were accessible and file transfers still work. But logging into the mycloud interface shows the raid array is "degraded", however the SMART data for both drives is "healthy". Googling this, people say I should be able to click a button to rebuild the RAID array under these conditions (I'm using a mirroring setup) but despite auto rebuild being turned on it hasn't fixed itself, and when I turn auto rebuild off I don't get the button other people say should be there. Is there a way to force the mycloud interface to perform a RAID rebuild, or will it result in losing the data to restore RAID integrity? Some people say you should replace a drive, but if both drives are healthy how do I choose a drive to replace? Seems silly. Plus the smart data for the drives I don't know how to interpret this though No idea how to fix this or interpret the information. Anyone got ideas?

I have been enjoying the TV (model in title) with my dad but I have wondered if adding a subwoofer to its sound setup would give it a more... cinema quality sound? The sounbar sounds pretty good (certainly a lot better than integrated speaker) but it doesn't have the ability to produce those powerful low frequencies. I can't see a suitable black AV jack at the back for a subwoofer, but Panasonic sells wireless Subwoofers on their website (sadly I can't find them standalone, only in 2.1 of more config). But this tells me I could potentially get one unit to connect to the TV and just... pop subwoofer ranges into my home TV experience? Any ideas welcome, I know a fair bit about displays but audio is a little more finniky. Wouldn't say a budget because I don't even know what the range is for that kind of equipment yet, but guessing something decent is £100-400 GBP? Cheers.

A lot of people complain about how many different ways to use Linux there are, but I just got a Pixel6 today and it's yet another of the many many different forms of UI to control an android phone. I was used to the home button and touch return and task button, then I was used to the touchscreen versions of them, now I need to get used to them not being there at all. There was an app tray, then there wasn't, then it became optional, now it's back again. And the UI is different and "fragmented" between android manufacturers and the apps they package with the phones can be different. Might not be as severe as desktop Linux, but it goes to show that a lot of things people view as "too hard, should be more like what I already know" are just things people should take the time to learn if they actually want to move OS. Linux' DEs are not complete or perfect and there are valid criticisms, but a lot of the things people complain about on the reg are just "Not carbon copy of windows, how can I be expected to function?" then trying to say anyone who points out macos -> windows transitions for newbies of either and vice-versa also has a learning curve is just "part of why Linux will never be successful" If you're happy on windows, just stay on windows, if you want to try something else however, you have to first accept that it is not windows and work from there, which means spending time to learn it. My 2c. Ofc some Linux community members genuinely are exclusive and unhelpful, but I like to think there are a fair few good places for getting help like /r/linux4noobs, and even on /r/linux which has often been a bit extremist there have been compilations of specific complaints and issues linus & luke have had, and trying to work out what to suggest to developers of the software.

I bought an ASUS VG248QE years ago (2014) and it came with a DVI cable in the box which i have always thought was a little short (shorter than other DVI cables I've used). But if I tried to switch it for a DVI cable I already had or a HDMI cable it would restrict me to 60Hz refresh rate, and claim 144hz was "out of bounds". I ended up using it with display port instead, until recently when the display port on the display broke. Now I am stuck with one screen running 144hz and my secondary running at 60 which isn't ideal. But my brother is using my original DVI connector due to issues he has with his kit. Is there anywhere to get one of these high-bandwidth DVI connectors that's ideally longer than the 1 meter it came in out of the box?

This is a friend's computer: Win10 64-bit (EDIT: Version 21H1) I7-7700 GTX 1080 32GB DDR4 Alienware Desktop format motherboard and PSU of some kind (Prebuilt machine) Samsung EVO 860 2TB SSD - The only component that was not in the PC when he bought it. Symptoms: Computer turned on one day with no internet connectivity (can only connect to wifi due to house layout), windows device manager shows the devices but has errors. Bluetooth devices show the same error. Cannot connect the machine to the internet via phone tethering either (tho I couldn't help much here, he has an iPhone). Attempted fixes: He used a restore disk he made a year or two ago, to reinstall windows 10. The issue persisted at this point. Checkdisk in the command line ran and tried to fix an ungodly number of... files? Sectors? (440 million odd). This resolved the issue and he could connect to the internet once it had completed. But the next time he rebooted his PC the original problem came back. Now he can run it again (checkdisk) but it sometimes fixes the issue and sometimes does not. It takes like 5 hours to complete the checkdisk. He is in Windows right now and showing me the screen on his phone. The event viewer gave an event from the first time it occurred saying that "device pci [number] requires further installation" for the network adapter "intel r dual band wireless-ac3165". When he got it working the first time after a checkdisk he ran an update utility to check the driver version, it claimed no update was needed. But the error persisted again after a reboot anyway. I can't work out if there is genuinely an issue with the drivers, an issue with his SSD (which only affects his wifi/bluetooth drivers??) or some other issue. It's a very odd problem that i've never seen before.

I'm using an NH-15S with a 5800x! It's very happy with it. I got 15477 score in cinebench R23, with 1589 score in single core mode. Max temperature of 84c (I suspect the max it would ramp itself up to to get the best all-core clocks). It reported a power usage of 137w all core and 38w single core. Can't remember my max clocks, but I might go back and check a bit later. But yeah the NH15-S is super! And the chromax black version is out now (wasn't when I bought mine in december last year sadly) so it will meld nicely with a lot of case designs!

I had this issue recently on a gigabyte B550 board with evga supernova G2 650w. Turned out two things were off: 1: My wall socket was faulty (wiggling the plug caused arcing and caused a LOT of interference in my analog microphone, and even triggered a reboot once) 2: My 24-pin ATX power connector to the mobo wasn't QUITE in correctly. Since I pushed it in further (saw a slight gap which isn't there any more) the reboots have stopped completely.
